Cotton sampling head

Abstract

The invention relates to a cotton sampling head, particularly to a cotton sampling head provided with a round cutting type sampling cutter and a cotton sample claw. The sampling head is mainly composed of the cotton sampling cutter, a cutter holder, the cotton sample claw, a cotton sample claw rotary support, a driving wheel and an operating lever, wherein the cotton sampling cutter is fixed at the front end of the cutter holder, the rear end of the cutter holder is connected with the driving wheel through a fixing flange, the operating lever penetrates through the central hole of the driving wheel, a floating rotating shaft is installed at the front end of the operating lever, and the cotton sample claw is driven by a cotton sample claw driving board fixed on a bearing block. Round cutting type sampling can be achieved through the cotton sampling cutter, the cotton sample claw can grab cotton samples out after the cotton sample cutting and then release the cotton samples, namely, feeding forward and round cutting are performed simultaneously, the obtained cotton samples are in cake shapes, and the sampling depth can be adjusted freely as required.

Description

technical field [0001] The invention relates to a cotton sampling head, in particular to a cotton sampling head with a circular cutting type sampling knife and cotton sample claws. Background technique [0002] At present, cotton bale sampling in the world is mainly manual sampling and mechanical sampling, and mechanical sampling is mainly based on the hydraulic cotton cutting machine developed in the United States, but this method belongs to semi-automatic sampling. [0003] The sampling part in the hydraulic cotton cutting machine developed in the United States adopts a vertical parallel double-knife structure, and the distance between the two knives is 150mm. When sampling, the hydraulic valve controls the two knives to cut into the cotton bale from both sides of the bag body, and the movement from top to bottom will Two large openings about 254mm in length are cut on both sides of the cotton bale, and then cut horizontally with a knife manually, and then the cotton sampl...

AI Technical Summary

Problems solved by technology

[0006] The shortcomings and defects of the above two types: both can only obtain cotton samples on the surface of the cotton bale; it needs to be manually cut horizontally with a knife, and then the cotton samples are taken out manually, which cannot achieve automatic sampling; the depth of sampling is limited by the width of the blade, can not be adjusted

[0007] The existing cotton sampling heads with vertical parallel double-knife structure knives all use thin blades. These blades can only be inserted into the cotton bale vertically in one direction, and cannot perform cutting actions such as rotation.

In addition, when the blade of the prior art is inserted into the cotton bale, because the blade has a very small edge angle and both sides are attached to the cotton, the resistance is very large, and deep sampling cannot be realized.

[0008] The circular cutting type sampling of cotton bale still does not have relevant bibliographical record at present, is applicable to the cotton sampling head with circular cutting type sampling knife and cotton sample pawl that is suitable for circular cutting type sampling especially has no way of reporting, the sampling of prior art Sampling components in the device simply cannot be used in this situation
